SPECIFICATION forming part of Letters Patent No. 779,912, dated January10, 1905.

Application filed May 19, 1904. Serial No. 208,712.

To all whom, it may concern:

Be it known that I, SAMUEL OUR'IIs, a citizen of the United States,residing at Kirkwood, in the county of St. Louis and State of Missouri,have invented a certain new and useful Embossing-Press, of which thefollowing is such a full, clear, and exact description as will enableany one skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, forming part ofthisspecification.

My invention relates to improvements in that form of embossing-pressshown and described in Letters Patent No. 695, 542, granted to me March18, 1 902. I The object of my invention is to simplify and improve thegeneral construction of the press and also to render the operation ofthe various parts positive and to provide for their adjustment. 1n theaccompanying drawings,which illustrate one form of embossing-press madein accordance with my invention, Figure 1 is a front elevation. Fig. 2is an enlarged section, showing a detail of construction. Figs. 3 and 4are detail views showing the mechanism for actuating the paper-feed.Fig. 5 is a side elevation. Fig. 6, is an enlarged detail view. Fig. 7is an enlarged central vertical section through the main part of themachine. Fig. 8 is partly a top plan view and partly a section. Fig. 9is a sectional view Fig. 10 is an enlarged sectional view through oneend of the wiping-block, and Fig. 11 is an enlarged end view of theink-supplying roll.

- Like marks of reference refer to similar parts in the several views ofthe drawings.

15 is the base of the machine. Carried on the base 15 are'side frames 16and 17.

18 is the bed of the machine, the forward end of which is securedbetween the side frames 16 and 17. The rear end of the bed 18issupported by uprights 19, resting on the base 15.

' 20 is the main shaft of the machine. This shaft 20 is journaled in theside frames 16 and 17 and has secured to it a disk 14 and a gear-v wheel21. The disk 14 and gear-wheel 21 are each provided with a wrist-pin onwhich are journaled the lower ends of pitman-rods 22.

' 23 is a cross-piece carried by guide-rods 24, supported in the sideframes 16 and 17. The rods 24 are surrounded by coil-springs 25, whichnormally hold the cross-piece 23 in its raised position. The ends of thecross-piece 23 project through openings in the top of the side framesand are provided with hearingpins 26, through which the pitman-rods 22pass. The openings in the bearing-pins 26 are formed as shown in Fig. 2,so as to allow for the lateral movement of the pitman-rods 22.Surrounding the pins 26 are caps 27, having upwardly-extending annularpieces 28. Each of these annular pieces 28 is provided with an annulargroove in which is placed a ring 29, of rubber or other resilientmaterial. Within the ring 29 is a bearing-surface 30, which is adaptedto come in contact with a bearing-surface 31, formed in an annular stop32, secured on the upper end of the pitmanrod 22 by means of a nut 34.Surrounding the bearing-surface 31 is a bearing-surface 33, which isadapted to come in contact with the ring 29.

35 is a plunger, which works in aguide 36, carried between the sideframes 16 and 17. The upper end of this plunger is screw-threaded andpasses into an opening in the cross-piece 23. The plunger 35 can beadjusted by means of a nut 37 and is rigidly secured by means of alock-nut 38. The lower end of the plunger 35 is provided with an openingadapted to receive a short cylindrical stem 39 on a platen 40, which isadapted to make contact with the die, as will be hereinafter described.The cylindrical stem 39 is provided with an opening 41 to receive a pin42, which secures the platen 40 to the plunger 35. This opening 41 ismade in the form shown in Fig. 9, so as to allow the the platen 40 to beset either straight across the machine or at an angle.

43 represents clamps pivoted to the platen 40 at 44. These clamps 43 areadapted to secure a strip of cloth or other suitable material to theplaten 40.

Formed in the bed 18 are guideways 48, in which slides a bed-plate 49.This bed-plate 49 carries a die 50, which may be secured in position inthe same manner as the bearingblock 40 or in any other suitable manner.

Formed in the bottom of the bed 18 is a slot 51, through which extends adownward projection 52, carried by the sliding bed-plate 49. Pivoted tothis projection 52 is one end of a link 53, the opposite end of which ispivoted to an oscillating bar or arm 54. The lower end of this bar orarm 54 is pivoted at 55 to the base 15 of the machine. Pivoted to thearm 54 at 56 is one end of the yoke 57, the opposite end of which issecured to an eccentric-strap 58. This strap 58 surrounds an eccentric59, secured on the main shaft 20. vided with a roller 60, which bearsupon the strap 58,and thus imparts movement to the arm 54. The strap 58is provided with an enlarged portion 61, so that an idle point is formedwhen the bed-plate 49 is in its forward position, so that the die 50will remain at rest while the platen 40 is making contact therewith.

64 is the ink-receptacle, in which is journaled an ink-supply roll 65.This roll 65 is driven by a belt 66, passing around a pulley 67 on theshaft of the roll and around a second pulley 68 on a driving-shaft 69.The pulley 67 is loosely mounted on the shaft 70 of the inkingroll andis provided with a dog 71, engaging with a notch in the shaft 7 0, sothat the inkingroll will be driven in the direction of the arrow in Fig.11 when the pulley 67 is driven in one direction, but will not rotatethe roll when driven in the opposite direction.

72 is a scraping device for removing surplus ink from the roll 65.

Secured to the bed 18, immediately in front of the ink-receptacle 64,are apair of uprights 74, in which is journaled a rock-shaft 75. Thisrock-shaft 75 is provided with two arms 76. These arms 76 are providedwith lugs 77 and 78, through which pass rods 79. Surrounding each ofthese rods 79 is a coil-spring 80, the upper end of which rests againstthe lugs 78 and the lower end against a collar 81, secured to the rod79. J ournaled in the ends of the rods 79 is a shaft 82, carrying aninkingroll 83 and a pair of wheels 84, adapted to run upon a track 85,and thus guide the inking-roll 83 to the ink-supply roll 65,hereinbefore described.

86 is a coil-spring surrounding one end of the rock-shaft 75 and tendingto move the said rock-shaft 75 so as to swing the roll 83 into contactwith the roll 65. The rock-shaft 75 has rigidly secured to one end anarm 87, pivoted to an operating-rod 88. This rod 88 has secured to itslower end a roller 89, bearing on a cam 90 on the main shaft 20.

Secured to the bed 18 in front of the up right 74 are a pair of supports92 and 93. Moving in these supports 92 and 93 is the wiping-block 94. Asthis wiping-block 94 is similar to that shown in my patent abovereferred to, it will not be described in detail.

The eccentric'59 is pro-- The wiping-block 94 is actuated by means offingers 95, carried on a rock-shaft 96. In order to secure an adjustableconnection be tween the fingers 95 and the wiping-block 94, I providethe said wiping-block 94 with a sliding plate 91, which engages with thesaid fin' ger 95. This plate 91 has an overturned edge 97, through whichpasses a screw 98, which bears upon the top of the wiping-block. Byrotating this screw 98 the connection between the finger and thewiping-block may be adjusted. The screw 98 is secured in position by alock-nut 99. In order to hold the wiping-block in its raised position, Isecure to the guides 92 and 93 tubes 100. tubes is a spring 101, throughwhich 'passes a rod 102, having at its upper end a nut 103, bearing onthe top of said spring, and at its lower end being secured by a pin 104to the wiping-block 94. In order to operate the rock-shaft 96, I provideit with an arm 105, in the end of which is a set-screw 106. Thisset-screw 106 bears upon the upper end of rod 107, the lower end ofwhich is provided with a wheel 108, resting upon a cam 109 on the mainshaft 20.

Adjacent to the cam 109 is a second cam 110, cooperating with a roller111, carried on a rod 112. This rod 112 is secured, by means of a screw113 passing through a slot 114, to a loop 115. This loop 115 is providedwith a rack 116, which engages with a gear-wheel 117. This gear-wheel117 is journaled in one of a pair of brackets 118 and has looselyjournaled in it one end of a shaft 119, carrying a paper-roll 120. Theshaft 119 is also provided with a ratchet-wheel 121, which is connectedwith the gear-wheel 117 by means of a dog 122, so that when the saidgear-wheel 117 rotates in one direction the paper-roll 120 will berotated with it; but when it rotates in the opposite direction the roll120 remains stationary. Journaled in the brackets 118 is a paper-guide123. This paper-guide 123 is also provided-with. a pawl 124, whichengages with a ratchet-wheel 125 on the paperroll 120, so as topositively prevent any rotation of the roll in the wrong direction. 126is a second paper-roll, which is journaled in brackets 127, carried bythe side frames 16 and 17.

The driving-shaft 69, hereinbefore referred to, is journaled in the sideframes 16 and 17 and also in a support 128, carried by the base 15. Thesaid shaft has secured to it between the side frame 16 and the support128 a beltwheel 129, by means of which the press is driven. The shaft 69is provided with a spurwheel 130, which meshes with the gear-wheel 21,hereinbefore described. This spurewheel 130 may either be securedrigidly to the shaft 96, or it may be loosely mounted thereon andsecured thereto at will by means of a frictionclutch 132, as shown inFig. 8. Extending from this friction-clutch 132 are connections In eachof these 133, provided with a handle 134, Fig. 1, within reach of theoperator.

The operation of my press is as follows: The ink for supplying the dieis placed in the ink-receptacle 64, and paper for wiping the said die iswound on the paper-roll 126 and passes thence down to the paper-guide123 and around the wiping-block 94 to the paper-feeding roll 120. Afterthe machine is started in operation the sliding bed-plate 49, carryingthe die, is carried to the rear of the machine. The inking-roll, 83after being brought in contact with the ink-supply roll transferssufficient ink to the die 50 to completely cover the face thereof. Asthe die 50 passes forward the wiping-block 94 carries the strip of paperdown against the face of the die, so that in its forward movement theink is removed from the face of the die and left only in the engravedportions thereof. The bed-plate 49 is carried forward by the movement ofthe arm 54, and as it nears its forward limit the rear end of the link53 drops in position, so that the movement of the bed-plate will becomparatively slow. As soon as the bed-plate has reached its extremefront position, with the die 50 directly beneath the block 40, theroller 60 will reach the enlarged portion 61 of the eccentric-strap, sothat the die 50 will remain stationary, while the pitman-rods 22 drawthe cross-piece 23, and consequently the block 40, downward, so that thesaid block comes in contact with the die to print the character engravedthereon. As the bearing-surface 33 of the cap 32 comes in contact withthe ring 29 before the bearing-surfaces 30 and 31 come together, themovement of the press will be noiseless.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, is

1. In an embossing-press, the combination with a reciprocating die, of aplaten cooperating therewith, a rock-shaft, an arm carried by saidrock-shaft, a pair of lugs on said arm, a rod slidingly mounted in saidlugs, an abutment on said rod, a spring surrounding said rod betweensaid abutment and one of said lugs, an inking-roll journaled in saidrod, and a wiping device for said die.
